The heating system at home chasnogo small area (80 sq.m.) has its own specifics. As a rule, these houses are no separate facilities for the item and placing the boiler equipment, have to save every square decimeter square. If this circumstance is of importance to you, the best option for heating homes chasnogo, in our opinion, is a system with a boiler mounted, dual-or single-loop. Modern hanging pots have a volume slightly greater than that of a kitchen cabinet can be hung in any convenient place (not necessarily in the kitchen) and contain all necessary components of the boiler room: circulation pump, expansion tank, safety valve, security, etc. Almost all mounted boilers can automatically resume work if the electricity is turned off and then re-fed. Double-circuit flow-through boilers have heat exchanger or storage built boiler for hot water. Mounted boilers are open or closed combustion chamber.

Closed combustion chamber allows the combustion gases can not vertical chimney, the device is very expensive, and in coaxial horizontal chimney, directly over the wall at home. This eliminates the need for a separate vent through which the boiler must enter the air required for combustion gas. This role is performed by the outer shell chimney. This design has a chimney is called "pipe in pipe". Another important advantage is mounted boilers special design of the burners, which are relatively insensitive to fluctuations in gas pressure in the pipeline. Of course, the heat capacity of the boiler will depend on the gas pressure, but burner wear this does not increase and get burned it will not be threatened. The latter property distinguishes the floor-mounted boilers from boilers with atmospheric burners, which under a reduced pressure gas can be "landing" of the flame on the burner and it burned. Power is mounted boilers from 12 to 35 kW, and the performance of hot water flow heaters of double-circuit boilers from 8 to 15 L / min.
